Matchup: Pitching

Yankees: The depth in the starting rotation makes this a formidable group. Only the Rangers' rotation had more wins, and only the Seattle Mariners logged more starters' innings. The rotation had a collective 4.05 ERA, better than the Orioles' 4.42 mark. But without the injured Mariano Rivera, the Yankees' bullpen hasn¿t been as dominant (3.43 ERA, seventh in the AL) as it has in past years. Orioles: The bullpen has earned all of its superlatives. The rotation gets one adjective: Fluctuating. A dozen pitchers have started at least two games for the Orioles, and only one pitcher has started more than 20 times for the club this season: Taiwanese rookie Wei-Yin Chen. The rotation would get a huge boost if Jason Hammel (8-6, 3.43 ERA), is healthy for this round. He hasn't pitched in a big league game since experiencing pain in his surgically repaired right knee Sept. 11. Edge: Yankees
